Introduction: Short Tandem Repeats (STRs) are defined as short lengths of 2-7 base pairs spreading through human genome which due to their highly diverse individually distribution are widely applied for identity detection and other forensic medicine purposes. Burdening considerable costs by the conventional methods such as capillary electrophoresis, we aimed to compare concomitant usage of multiplex PCR and denaturing high-performance liquid chromatography (DHPLC) as cheap, fast, highly accurate, and more accessible methods, with capillary electrophoresis (CE) to evaluate their potential for early screening of STRs.
Materials And Methods: The present study randomly included 20 blood samples from the subjects referred to forensic medicine of Semnan, Iran. Read More

Background: Bisphenol F (BPF) and bisphenol S (BPS) are increasingly used as alternatives to endocrine disrupting chemical bisphenol A (BPA). Evidence from in vitro and animal studies demonstrates that BPA, BPF and BPS induce oxidative stress, a proposed mechanism that is relevant to various adverse health effects. Evaluation in humans is hampered by the potentially high within-subject variability of urinary measurements. Read More

Glycyrrhizin, a triterpenoid compound, has been reported to be an anti-inflammatory agent for the treatment of a variety of inflammatory diseases including hepatitis. However, the mechanism by which glycyrrhizin inhibits inflammation is unclear. Using a Con A-induced hepatitis model in mice, we found that administration of glycyrrhizin ameliorates Con A-induced liver injury, which manifests as reduction in the production of inflammatory cytokines IFN-γ, IL-6 and IL-17, as well as serum alanine aminotransferase (ALT).

Flow-cytometric detection of now termed measurable residual disease (MRD) in acute myeloid leukemia (AML) has proven to have an independent prognostic impact. In a previous multicenter study we developed protocols to accurately define leukemia-associated immunophenotypes (LAIPs) at diagnosis. It has, however, not been demonstrated whether the use of the defined LAIPs in the same multicenter setting results in a high concordance between centers in MRD assessment. Read More

Background: Toe-walking is a normal variant in children up to 3 years of age but beyond this a diagnosis of idiopathic toe-walking (ITW) must be considered. ITW is an umbrella term that covers all cases of toe-walking without any diagnosed underlying medical condition and before assigning these diagnosis potential differential diagnoses such as cerebral palsy, peripheral neuropathy, spinal dysraphism and myopathy must be ruled out. Gait laboratory assessment (GLA) is thought to be useful in the evaluation of ITW, and kinematic, kinetic and electromyography features associated with ITW have been described. Read More

The potential medical risks to egg donors, in addition to the concern over the commodification of life, has led to debates surrounding the ethics of paying donors. In Canada, payment for eggs is prohibited by law; however, what is considered payment is contentious and has yet to be defined. The lack of legislative clarity coupled with increased ethical concerns over paying a donor has shifted egg donation from a medically-controlled procedure to a legal and social endeavor involving multiple professionals.

This is a selective review of the work of Buchsbaum and colleagues. It revisits and pays tribute to four decades of publications employing positron emission tomography (PET) with fluorodeoxyglucose (FDG) to examine the neurobiology of schizophrenia-spectrum disorders (including schizotypal personality disorder (SPD) and schizophrenia). Beginning with a landmark FDG-PET study in 1982 reporting hypofrontality in unmedicated schizophrenia patients, Buchsbaum and colleagues published high-impact work on regional glucose metabolic rate (GMR) abnormalities in the spectrum.

Caffeine intake is associated with a reduced risk developing non-alcoholic fatty liver disease (NAFLD), but the underlying molecular mechanisms remain to be fully elucidated. We report here that caffeine markedly improved high fat diet-induced NAFLD in mice resulting in a 10-fold increase in circulating IL-6 levels, leading to STAT3 activation in the liver. Interestingly, the expression of IL-6 mRNA was not increased in the liver, but increased substantially in the muscles of caffeine-treated mice. Read More

To date, numerical simulations of the brain tissue have been limited by their lack of realism and flexibility. The purpose of this work is to propose a controlled and flexible generative model for brain cell morphology and an efficient computational pipeline for the reliable and robust simulation of realistic cellular structures with application to numerical simulation of intra-cellular diffusion-weighted MR (DW-MR) signal features. Inspired by the advances in computational neuroscience for modelling brain cells, we propose a generative model that enables users to simulate molecular diffusion within realistic digital brain cells, such as neurons, in a completely controlled and flexible fashion.

Associative memory plays a key role in everyday functioning, but it declines with normal aging as well as due to various pathological states and conditions, thus impairing quality of life. Associative memory enhancement via neurostimulation over frontal areas resulted in limited success, while posterior stimulation sites seemed to be more promising. We hypothesized that anodal transcranial direct current stimulation (tDCS) of parietal areas would lead to higher performance in associative memory due to high connectivity between posterior parietal cortex (PPC) and hippocampus.
